Odrive 3.6 Schematic Hot! Page
The microcontroller cannot spin a motor by itself. It sends small signals to a chip. This chip acts as the bridge. It turns the brain's commands into loud, high-power signals. 2. The Power MOSFETs
Based on the schematics, here are the core components used in the v3.6 design: Microcontroller: STM32F405RGT6 Gate Driver: ODrive Community Power Variants: The v3.6 comes in (12V-24V range) and (12V-56V range) versions ODrive Europe Design Status ODrive v3.6 is currently listed as NRND (Not Recommended for New Designs) ODrive Europe
Keep gate traces as short and wide as possible (minimum 15-20 mils width).
Each motor channel features six N-channel Power MOSFETs arranged into three half-bridges (Phase A, B, and C). Uses low odrive 3.6 schematic

odriverobotics/ODriveHardware: High performance motor control
The ODrive 3.6 schematic can process continuous currents exceeding 60 Amps per phase under proper cooling. The microcontroller cannot spin a motor by itself
This is the most complex part of the . Each motor has a 3-phase inverter bridge. For Motor 0, look for:
gate drivers, which handle the high-current switching required for BLDC motors. Current Sensing:
The small voltage drop developed across these shunts is routed back into the internal operational amplifiers of the DRV8301. The differential current sense signals are amplified and fed straight into the fast Analog-to-Digital Converter (ADC) peripheral pins of the STM32 MCU. Voltage Sensing It turns the brain's commands into loud, high-power signals
: RC snubber filters are optionally populated across the drain and source of the power FETs to suppress ringing and electromagnetic interference (EMI) during high-frequency switching transitions. 5. Phase Current and Voltage Sensing Architecture
The ODrive exposes J4 (The User I/O header). The schematic shows exactly what each pin does:
Features dual motor outputs (M0 and M1) capable of 120A peak current per motor. It includes current shunt resistors (0.0005 ) for precise torque control. Brake Resistor Interface:
The small voltage drop across these shunts is routed via differential traces directly to the internal programmable-gain operational amplifiers inside the DRV8301.
